What are the climatic characteristics of the great cold solar terms?

The Great Cold is the last of the 24 solar terms.

Climatic characteristics of severe cold solar terms: rain, snow, strong wind and low temperature.

There is often a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of northwest wind and constantly supplemented cold air, China will have a sustained low temperature. Like slight cold, great cold is also a solar term indicating the degree of cold weather. Modern meteorological observation records show that in some parts of China, severe cold is not as good as mild cold. Railway, post and telecommunications, petroleum, shipping and other departments should pay special attention to take measures to prevent strong winds, heavy snow and other bad weather as soon as possible.
